Historic Assessment of Compatibility
Several properties of compatibility discussed in the previous sections may not be relevant to all the fields of study in which compatibility between objects or concepts is used to analyze information and assist in decision making. An understanding the significance of these properties, however, is necessary for building a general classification framework. In this section we present a brief examination of the measurement and use of compatibility in taxonomy, psychology, and statistics. In these disciplines, the focus has been on the similarity of objects and the assessment has generally been based upon the commonality of crisp sets of attributes possessed by the objects. The analysis of crisp sets has often provided the basis for a generalization to measurement of fuzzy sets and we will focus on crisp techniques that have been subsequently applied to the assessment of the compatibility of objects whose properties are described by fuzzy sets.
